[jlsherrill]

Also fixes HMS-8716

Summary

splits the red hat repos json file into multiple
also adds 6 new repos, supplementary repos for 8,9,10 x86_64 and aarm64.
repositories are largely organized by feature, while splitting RHEL into mulitple versions as well.

Testing steps

make repos-import

make db-cli-connect

content=# select count(*) from repositories where origin = 'red_hat';
 count 
-------
    31
(1 row)

On main, this would be 25, 25 + 6 supplementary repos is 31.

This looks good. Just to differentiate from community repos, can we rename the directory to something like snapshotted_repos/redhat?
